Chapter 4 feels really rough right now, least in the version i played. Lots of calls to various relationship names were bugged out. Could sort of guess what it was intended to be, usually Uncle / Aunt / etc. And i guess some of the dialog suddenly had a different tone. The aunt suddenly saying "tho", or the MC saying "uber". Idk.... maybe i'm overly sensitive.
I generally liked it so far; The pull and chase of all the relationships were mildly frustrating, but keep some tension. Like; you definitely don't want insta corrupt harem stuff, but the hot and cold nature of the characters... maybe is a bit too realistic lol.
